A new single-component photocatalyst for the reduction of water to H2, a dichloro(dpbpy)platinum(II) derivative (dpbpy = 4,4′-diphenyl-2,2′-bipyridine) tethered to four pendant viologen acceptors (1), is shown to exhibit twice higher photocatalytic efficiency than the previously reported dichloro(bpy)-platinum(II) analog (2; bpy = 2,2′-bipyridine), consistent with the higher absorptivity of 1 at the metal-to-ligand charge transfer (1MLCT) band due to the larger π-conjugation in dpbpy relative to bpy.

The kinetics of oxidation of cis-[PtCl2L2] (L = py, 3-methyl-, 3- and 4-chloro-, 3- and 4-cyanopyridine) by [AuCl4]- in the presence of [NEt4]Cl and of reduction of cis-[PtCl4L2] by [NEt4]I were studied in MeCN. The rate law for the oxidation reaction was rate = k3[PtCl2L2][AuCl4-][Cl-], where k3 was unaffected by changes in L and had a value ∼100 times higher than that previously found for related phenanthrolineplatinum(II) complexes. The rate law for the reduction reaction was rate = k2[PtCl4L2][I-], where k2 was influenced by the basicity of L, as in related phenanthrolineplatinum(IV) complexes. The kinetic results were discussed in terms of σ and π interactions between the Pt and L.

Author is Giese, Bernd; Deacon, Glen B.; Kuduk-Jaworska, Janina; McNaughton, Don.

There is considerable interest in the development of novel platinum-based anticancer drugs that overcome the disadvantages associated with the widely used drug cisplatin, which are its inactivity against some types of tumors and its toxic side effects. In this study we show the suitability of normal Raman spectroscopy (NRS) and surface enhanced Raman spectroscopy (SERS), assisted by d. functional theor. (DFT) calculations, for the characterization of Pt complexes. The Pt complexes studied include the established drugs cisplatin and carboplatin, as well as five novel Pt complexes with anticancer activity. DFT calculations at the B3LYP/LanL2DZ level are a good prediction of the exptl. NRS spectra of small and medium sized Pt complexes. The use of SERS allows the investigation of Pt complexes at physiol. concentrations, and the binding strengths of the different ligands can be determined The formation of pos. charged hydrolysis products may be necessary for SERS activity. The existing group in the hydrolysis reaction can be identified.

Given the requirements of high sensitivity and spatial resolution, the development of new positron emission tomog. (PET) agents is required for PET renog. The objective of this study was to investigate a new fluorine-18 labeled hippurate analog of picolinamide, N-(6-[18F]Fluoropyridin-3-yl)glycine, as a new renal PET agent for evaluating renal function. N-(6-[18F]Fluoropyridin-3-yl)glycine was prepared via a two-step reaction, including the nucleophilic substitution reaction of Br with 18F using Me 2-(6-bromonicotinamido)acetate as a precursor followed the hydrolysis with sodium hydroxide and purification by preparative-HPLC. The in vitro and in vivo stability were determined using HPLC, and the plasma protein binding (PPB) and erythrocyte uptake of N-(6-[18F]Fluoropyridin-3-yl)glycine were determined using blood collected from healthy rats at 5 min post-injection. Biodistribution and dynamic micro-PET/CT imaging studies were conducted in healthy rats. N-(6-[18F]Fluoropyridin-3-yl)glycine demonstrated good stability both in vitro and in vivo. The results of the biodistribution and dynamic micro-PET/CT imaging studies in normal rats indicated that N-(6-[18F]Fluoropyridin-3-yl)glycine was rapidly and exclusively excreted via the renal-urinary pathway. N-(6-[18F]Fluoropyridin-3-yl)glycine is has been shown to be a promising renal PET agent and warrants further evaluation of renal function.
